bootstrap accordion how to check which panel is active

I am using Bootstrap's accordion widget to contain several forms i.e. each panel contains one form. When the last panel is selected, the data from the other panels is meant to be posted which will be used to graph the data. However, I am unable to get to the posting part as I cannot figure out which panel is currently selected. I know that this has to do with a class of active or inactive, but I don't think bootstrap's accordion supports that functionality unlike jquery accordion.
I am trying to figure out the first part i.e. check if the user has clicked on the last panel. In my HTML code it has an id of #results. Here's a jsfiddle that demonstrates the issue I am facing. It does not seem to trigger the second alert function when the user clicks on the #results tag, not sure why.
Sample javascript code:
$('#accordion').on('show.bs.collapse', function () {
$('#results').click(function () {
alert("works"); //testing purposes
});
});

Why don't you do?
$('#results').click(function (){
alert("clicked");
});
Just remove the accordion function and you'll get the on click event directly

Is this what you want?
Fiddle: Demo
take this outside the on function
$('#results').click(function (){
alert("clicked");
});

This is an old thread but I wanted to post an answer as the expected result is not suggested.
What you need to do here is to handle the currently selected collapse items with the event handler. If you use the this keyword for this, you can access the values of the selected object (For example only one item in the form).
Here you can get the $(".collapse") element.
You can get the index number of the active item with $(this).parent().index().
Likewise, you can get the id of the active item with $(this).attr('id').
Your jQuery structure would be:
$(".collapse").on('show.bs.collapse', function(){
//0,1,2,etc..
var index = $(this).parent().index();
//collapseOne, collapseTwo, etc..
var id = $(this).attr('id')
//alert('Index: ' + index + '\nItem Id: ' + id );
console.log('Index: ' + index)
console.log('Item Id: ' + id)
if(id === 'collapseFour')
{
var username = $('#username').val();
var email = $('#email').val();
var age = $('#age').val();
//here you can check the data from the form
$("#result").html("<p> UserName: " + username + "</p> <p> EMail: " + email + "</p> <p> Age: " + age + "</p>");
}
});
I've included a working example here for you (jsfiddle).

$('#accordion').on('show.bs.collapse', function (accordion) {
var $activeCard = $(accordion.delegateTarget.children);
});
or
$('#accordion').on('show.bs.collapse', function () {
var $activeCard = $(this.children);
});

Keep appending link value to an input box

I'd like to know how to append link values to an input box. But I can't figure out how to append a new link value to the old one, separated by a space [Fiddle].
<input id="a_input_id" type="text">
<a href="" class="special_field_link">#ABC<a>
<a href="" class="special_field_link">#DEF<a>
<script>
$(function(){
$('.special_field_link').live('click', function()
{
$('#a_input_id').val($(this).html() + '');
return false;
});
});
Should I use something like:
var cur_val = $('#a_input_id').val($(this).html() + '');
if(cur_val)
$('#a_input_id').val(cur_val + "," + new_val);
else
$('#a_input_id').val(new_val);
Your help would be appreciate.

You can use like this,
$('.special_field_link').click(function (e) {
e.preventDefault();
$('#a_input_id').val($('#a_input_id').val()+" "+$(this).html());
});
Use event.preventDefault() to prevent the default click event of anchor. In each click you need to get the current input value, if you want to retain those. In your code, it was overwriting the old with the new values.
Fiddle

If you want to append the value, you could do:
var input = $('#a_input_id');
input.val(input.val() + $(this).html());
And note .live is deprecated, you'd better use .on instead if you switch to a new version of jQuery.
THE DEMO.

You could go with:
http://fiddle.jshell.net/s8nUh/149/
$(function()
{
$('.special_field_link').live('click', function()
{
var original = $('#a_input_id').val();
var val = original + ',' + $(this).html();
val = val.replace(/(^,)|(,$)/g, "");
$('#a_input_id').val(val);
return false;
});
});

$(function(){
$('.special_field_link').live('click', function()
{
$('#a_input_id').val($('#a_input_id').val() + $(this).html() + '');
return false;
});
});
To use best practices, its better to cache jquery object for anchor and also avoid using return false.
$(function(){
var txt$ = $('#a_input_id');
$('.special_field_link').live('click', function()
{
txt$.val(txt$.val() + $(this).html());
event.preventDefault();
});
});

Repeatable Blocks

I currently have a bit of JS which will generate buttons based on the data attribute stored in the HTML, which will generate 2 buttons:
Plus Button to add a repeatable block(Will/should only display a plus button if there is only one block)
A minus button to remove the repeatable field(will/should show when there is more than one blocks)
Thing is, I have the buttons working fine, but when I added the event handlers for them to do as I ask, and click on them nothing happens, am not sure why and hopefully you can point me in the right direction.
Regards!
P.S jQuery Code
$('.glyphicon-plus-sign').on("click", function () {
prevInput = $(this).prev('input');
count = $(prevInput).attr('data-count');
countIncremented = count++;
br = '<br/><br/>';
inputElement = '<input type="' + $(prevInput).attr("type") + '" name="' + $(prevInput).attr("name") + countIncremented + '" data-count="' + countIncremented + '"/>';
$(br + inputElement + plusMinusButtons).insertAfter('.' + $(prevInput).attr("name") + ':last');
});
$('.glyphicon-minus-sign').on("click", function () {
prevInput = $(this).prev('input');
$(this).remove(prevInput).remove(this);
});
$("button").click(function () {
console.log("here");
x = $('#form').serializeArray();
$.each(x, function (i, field) {
console.log(field.name + ":" + field.value + " ");
});

I currently have a bit of JS which will generate buttons
Dynamically adding buttons means you have to approach events a little differently. You need to do the following:
$('body').on("click", '.glyphicon-minus-sign', function () {
...
}
$('body').on("click", '.glyphicon-plus-sign', function () {
...
}
Essentially, you are now listening to clicks on the body element, instead of the actual buttons (which might not actually exist yet). Any other statically created buttons aren't affected.

Why is my JQuery function not triggered on a cloned element when the event becomes "true"?

I have been making this form that must enable the back-end user to create new questions for users to answer. The form is cloned and appended to a div (selector #content) successfully after the first .on(click) event, but it won't duplicate the form again if the cloned button is pressed. The .on(change) event applied to my drop-down selection does change the content of respective divs like it is supposed to, but only on the original form.
Here's the JQuery code:
$(document).ready(function () {
$('.addAnswer').on("click", function () {
var idx = $('#mp div[name^="antwoord"]:last').index() + 1;
$clone = $('#mp div[name^="antwoord"]:first').clone(true, true).attr('class', 'answer content_' + idx);
$('.removeAnswer').show;
$('#mp').append($clone);
$('.answer:last').each(function () {
$('b:last').empty();
$('b:last').prepend(String.fromCharCode(64 + idx) + ". ")
$('.addAnswer').on("click", function () {
idx++;
});
});
if (idx == 2) {
$('.removeAnswer').show();
}
});
$('.nextq').click(function () {
var newqid = $('#content form:last').index() + 1;
$('.done, .nextq, .remove').hide();
$('#content').append('<hr>');
$('#content').append($('form').html()).attr('class', 'q_' + newqid);
$('.nextq').on("click", function () {
newqid++;
});
$('.done:last, .nextq:last, .remove:last').show();
return false;
});
$('.group').hide();
$('#text:last').show();
$('.select:last').on("change", function () {
$('.group').hide();
$('#' + $(this).val() + ':last').fadeIn();
$('button.' + $(this).val() + ':last').fadeIn();
});
});
Because I thought posting the whole HTML template would be a tad bit too much, I provided a JSFiddle for you people.
One extra question for the ones that are feeling kind: In the JQuery code it is seen that the contents of the HTML are being parsed using .html() and appended with .append.(Line 33 on the JSFiddle) As the .on(change) function switches the contents of the divisions it should change, .html() sees those changes and takes those along with it. I'd like the .on(click) function to append the div's content in its original state, unchanged by the changes made beforehand by the back-end user. Any help with this would be much obliged.

In order to have jQuery trigger on new elements you would do something like
$( document ).on( "click", "<your id or class>", function() {
//Do stuff
});

How to have Jquery blur trigger on everything except hyperlinks/input buttons

I'm having a slight issue getting a jquery action to function ideally. Currently everything is working properly on a blur from a particular field, which is called "person_email". The issue is that if the end user does this, and decides to click a hyperlink for example on the rest of the page that jquery from the blur triggers, the user see's this briefly, and then continues to the corresponding link.
Ideally this would work that the blur would only trigger if a hyperlink was not clicked.
var $email = $("#person_email");
var $hint = $("#hint_edit");
$email.on('blur',function() {
$hint.hide; // Hide the hint
$(this).mailcheck({
suggested: function(element, suggestion) {
// First error - Fill in/show entire hint element
var suggestion = "Did you mean: <span class='suggestion'>" +
"<span class='address'>" + "</span>" +
"<a href='#' class='domain'>" + suggestion.address +
"#" + suggestion.domain + "</a></span>?";
$hint.html(suggestion).fadeIn(150);
}
});
});
$hint.on('click', '.domain', function() {
// On click, fill in the field with the suggestion and remove the hint
$email.val($(".suggestion").text());
$hint.fadeOut(200, function() {
$(this).empty();
});
return false;
});
})

I assume you want off
$("a").on("click",function() {
$email.off();
});
